Johnson's call-up deepens Miami's CB pool as Storm Duck recovers. He'll be asked to contribute in sub packages and on the outside against the Chargers.

Johnson’s elevation adds CB depth as Armstrong’s IR/exit leaves a rotation hole and Duck is questionable, potentially shaping nickel coverage and third-down packages.

Johnson returns to the Dolphins' practice squad after a brief 53-man stint was cut short by JuJu Brents' waivers. His 6'3" frame adds length and veteran depth behind Miami's boundary corps, providing a reliable option for practice reps and potential coverage scenarios as Brents competes for outside snaps.

Isaiah Johnson, a practice-squad-era player, was waived to clear room for Brents. His exit highlights the Dolphins' prioritization of upside in a depleted room, while Johnson’s departure underscores the competitive depth at cornerback and the team’s willingness to move on from former depth players in pursuit of athletic ceiling.

Isaiah Johnson was signed to the Miami Dolphins' practice squad and is part of the team's efforts to bolster their secondary as they navigate injuries and roster changes throughout the season.
